Description des sous-ensembles
Wiring DECT base stations
Each base station is connected to an ISDN S0 (BRI) interface of an EXT1-S12 card, and uses
two pairs: 1 transmit pair and 1 reception pair (refer to document [6] (see Section1.3) for more
information).
A twisted cable or S0/T0 adaptor is required to connect DECT base stations.
